There are some docs about building the driver at http://www.intellinuxgraphics.org, but maybe Dan or one of the Debian guys could get intel_reg_dumper added to the package? It's really handy for debugging problems...

This happens in both cases (X running or > not). So just having X running in the background is enough to cause a hang, even if you do the suspend/resume cycle from the console? Yuck.
